The timer is a weekend. The failure modes are not. Uninvoiced time that silently double-counts against a Jira worklog, an invoice sequence with a gap in it, or a laptop that was asleep when the agent tried to log its hours are all problems you discover on invoice day, in front of a client. A business billing real money for hours generally decides that maintaining the thing that produces its invoices is not the hobby it wants.
